GLBINDBUFFERSBASE(3G)

okay so bestie, welcome to the GLBINDBUFFERSBASE(3G) manual page — the OpenGL glow-up for binding a whole squad of buffer objects to a sequence of indexed buffer targets. 💅✨

🌸 NAME 🌸

glBindBuffersBase — bind one or more buffer objects to a sequence of indexed buffer targets

---

🎀 C SPECIFICATION 🎀

void glBindBuffersBase(GLenum target, GLuint first, GLsizei count,
                       const GLuint *buffers);

---

🦋 PARAMETERS 🦋

• target — the target of the bind operation, bestie. It must be one of GL_ATOMIC_COUNTER_BUFFER, GL_TRANSFORM_FEEDBACK_BUFFER, GL_UNIFORM_BUFFER or GL_SHADER_STORAGE_BUFFER.
• first — the index of the first binding point within the array specified by target.
• count — the number of contiguous binding points to which to bind buffers.
• buffers — a pointer to an array of names of buffer objects to bind to the targets on the specified binding point, or NULL.

---

💖 DESCRIPTION 💖

So glBindBuffersBase binds a set of count buffer objects whose names are given in the array buffers to the count consecutive binding points starting from index first of the array of targets specified by target. It’s giving group-chat coordination for your buffers. 🫶

If buffers is NULL, then glBindBuffersBase unbinds any buffers that are currently bound to the referenced binding points.

Assuming no errors are generated, it is equivalent to the following pseudo-code, which calls glBindBufferBase(), with the exception that the non-indexed target is not changed by glBindBuffersBase:

for (i = 0; i < count; i++) {
    if (buffers != NULL) {
        glBindBufferBase(target, first + i, buffers[i]);
    } else {
        glBindBufferBase(target, first + i, 0);
    }
}

Heads up, bestie: each entry in buffers will be checked individually, and if found to be invalid, the state for that buffer binding index will not be changed and an error will be generated. However, the state for other buffer binding indices referenced by the command will still be updated. 💀

🌈 NOTES 🌈

glBindBuffersBase is available only if the GL version is 4.4 or higher. No earlier-version crumbs, sorry. 😭

---

🔥 ERRORS 🔥

• GL_INVALID_ENUM is generated if target is not GL_ATOMIC_COUNTER_BUFFER, GL_TRANSFORM_FEEDBACK_BUFFER, GL_UNIFORM_BUFFER or GL_SHADER_STORAGE_BUFFER.
• GL_INVALID_OPERATION is generated if first + count is greater than the number of target-specific indexed binding points.
• GL_INVALID_OPERATION is generated if any value in buffers is not zero or the name of an existing buffer object.

👑 VERSION SUPPORT 👑

Original table vibes, translated into a list because we don’t do tables here, bestie. The row label is Function / Feature Name, and the columns are OpenGL Version.

• OpenGL Version columns: 2.0, 2.1, 3.0, 3.1, 3.2, 3.3, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5
• glBindBuffersBase — 2.0: -; 2.1: -; 3.0: -; 3.1: -; 3.2: -; 3.3: -; 4.0: -; 4.1: -; 4.2: -; 4.3: -; 4.4: ✔; 4.5: ✔
